Bonnes Pratiques
- You can select an entire column or row by clicking the header (e.g. B:B), which will sum everything in that column.
- SUM ignores blank cells and cells with text, preventing common addition errors.
Erreurs à Éviter
- If any of the cells in the range contain error values (like #VALUE!), SUM will return that error. Use AGGREGATE or SUMIFS to ignore errors.
